Has this happened to you on Modern Warfare 3 online multiplayer?

Last night I turned level 77 and today I turned on my system and I found out I’m level 66. I had completely lost a lot of my challenges I had completed and some titles and emblems as well.

So I decided to check my theater vault to see some of my previous matches from last night and I was still 77 in them.

I’m not sure if its the severs or just some one that found a way to demote people.

I was thinking of calling Activison to see if they can do anything about it because it isn’t the first time it has happened to me.
